The relative performance of one geno- type is not identical in different environments due to genotype-environment interaction (G 9 E). Thus, for a breeding program to successfully develop culti- vars, it is fundamental that candidate elite-lines are tested in several target environments and that the data are analysed for yield, adaptability and stability. The objective of this work was to study the G 9 E for upland rice using a mixed model and, using the harmonic mean of relative performance of genotypic values (HMRPGV) method, to analyse cultivars and elite-lines over time to identify those that aggregate high grain yield (GY) with high genotypic adapt- ability and stability. A large dataset of ??value for cultivation and use trials?? collected by the Brazilian Agricultural Research Corporation (Embrapa) and collaborators from 1984 to 2010, involving seven states that represent upland rice crops in the Midwest, North and Northeast regions of Brazil, was used. The effect of location was shown to be more important than the effect of year for promoting crossover interaction. The CNA 8555 had the best GY associated with adaptability and stability, pre- senting a superiority of 13.28 % above the general mean of all elite-lines. Using already-released cul- tivars and potential elite-lines, the generalised linear regression analysis revealed significant progress of the stability and adaptability associated with GY over time. The HMRPGV method was shown to be an important tool and allowed identification of three elite-lines in the Embrapa pipeline (AB 062008, AB 062041 and AB 062037), each with high stability, adaptability and yield potential to be released commercially.

The oxisols and ultisols of the tropics usually are less fertile than the soils of temperate regions. Some soybean varieties cultivated in the tropics are more tolerant to high Al and Mn concentrations in acid soils than wheat. They may even grow relatively well with less fertilizer, but to attain high productivity levels they need a large amount of inputs. These acidic and higly weahered soils may produce high yields after liming and a corrective fertilization for phosphorus and sometimes potassium. However, after several years of soybean-wheat double cropping on these soils, there has beean a gradual reduction in yields even with large amounts of inputs. This decrease can not be explained by low soil fertility, since chemical analysis shows high nutrients availability. It may be mainly atributed to poor soil tilth due to excessive plowing and disking, and continuous soybean-wheat doble cropping without a crop rotation. Different from the cold regions, where in winter no crops are grown and the soil is covered by snow, the tropics are characterized by year round cultivation. This year round systems is used in regions with enough rainfall or where irrigation is possible in the dry season, since there are no serious temperature and light limitations. However, continuous cultivation of these two crops led to compacted soil and high erosion, in addition to an increase in plant diseases an insect problems. These problems were partially overcome by some farmers who successfully adopted the no-till cultivation ...
